I was looking for the same thing, but found that tasks' log level is hardcoded. It is fixed
by MAPREDUCE-336 (in 0.21).

Subject: Change logging level of task attempts

Hi Users,
How do I change the log4j logging level of task attempts (the information dumped in syslog)
to DEBUG?
I tried setting log4j.logger.org.apache.hadoop.mapred.TaskTracker to Debug, but that didnt
help.

I would like to avoid cluster restart. Hoping its possible to over ride the INFO level, which
seems to be default, from command line.
